Abstract
Building on the recent discovery of the first candidate black hole operator in $\mathcal{N}=4$ super-Yang-Mills, we explore the near-supersymmetric aspects of the theory that capture lightly excited, highly stringy black holes. We extend the superspace formalism describing the classically supersymmetric (1/16-BPS) sector of $\mathcal{N}=4$ super-Yang-Mills and compute a large number of one-loop anomalous dimensions. Despite being in the highly stringy regime, we find hints of a gap in the spectrum, similar to that found by a gravitational path integral. We also determine the actual expression of the first candidate black hole operator at weak gauge coupling, going beyond the cohomological construction.
List of changes
-
We added footnote 4 specifying the regime of our discussion.
-
We added footnote 5 showing that the strict large N limit is well-defined in the space of BPS words.
-
We thank the referee for pointing it out. We rephrased our statement in Sec. 5.1.
